Benefits of technology

"The present invention is an electromagnetic rocking chair that uses a changing magnetic field and a fixed magnetic field to make the chair seat rock back and forth. The chair is made up of a base, chair seat, two fixed rods, and two suspension rods. Permanent magnets and electromagnets are used to create the interaction force between the changing magnetic field on the base and the fixed magnetic field on the bottom of the chair seat. Displacement sensors and coils are connected to a control circuit for sensing and adjusting the displacement of the chair seat. The chair has the advantages of a simple and stable running, no noise, and adjustable rocking amplitude."

Abstract

An electromagnetic rocking chair comprises a base, a chair seat, two fixed rods, and two suspension rods. Each of the fixed rods has a lower end fixed on one end of the base, and a transverse shaft is fixed on both upper ends of the fixed rods. An upper end of the respective suspension rods is pivotally connected to the transverse shaft, and the chair seat is disposed between the two suspension rods. A permanent magnet is disposed at the lower end of one of the suspension rods, and under the permanent magnet are disposed two electromagnets fixed on the base. On the base are further fixed two displacement sensors. The two electromagnets and two displacement sensors are connected to a control circuit on a circuit board. The electromagnetic rocking chair has advantages of simple and reasonable structure design, stable running, no noise, adjusting rocking amplitude and the like.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a rocking chair; and more particularly to an electromagnetic rocking chair.[0003]2. Description of the Prior Art[0004]Conventionally, an electric rocking chair utilizes a transmission mechanism (essentially including motor / gears / transmission rods, and etc) to drive the suspension parts of the chair so as to make the chair rock back and forth. However, such a structure suffers from the drawbacks of complicated structure and large noise.[0005]The present invention has arisen to mitigate and / or obviate the afore-described disadvantages.SUMMARY OF THE INVENTION[0006]The primary objective of the present invention is to provide an electromagnetic rocking chair which utilizes an interaction force between a changing magnetic field on the base and a fixed magnetic field on a bottom of the chair seat to make the chair seat rock back and forth around a suspension point.[0007]To achieve the above ob...
